Description

Called to indicate that the buffer operations between here and a call to gtkTextBufferEndUserAction are part of a single user-visible operation. The operations between gtkTextBufferBeginUserAction and gtkTextBufferEndUserAction can then be grouped when creating an undo stack. GtkTextBuffer maintains a count of calls to gtkTextBufferBeginUserAction that have not been closed with a call to gtkTextBufferEndUserAction, and emits the "begin-user-action" and "end-user-action" signals only for the outermost pair of calls. This allows you to build user actions from other user actions.

Usage

Arguments

Details

The "interactive" buffer mutation functions, such as gtkTextBufferInsertInteractive, automatically call begin/end user action around the buffer operations they perform, so there's no need to add extra calls if you user action consists solely of a single call to one of those functions.
